Will pregnant women do X -rays and CT examinations will affect their baby?Come and listen to what the doctor says!

One night on duty, a pregnant woman riding a motorcycle had a car accident, and the ambulance quickly sent her to the hospital.In order to quickly judge the condition, it took a few minutes to make her abdomen CT.The test results showed that her condition was very critical: the kidney arteries were falling off, the abdominal cavity bleed a lot, and the spleen was torn, and surgery must be performed immediately.

Fortunately, the surgery was smooth, and the mother and the baby were separated from danger.But the disadvantage of the United States is that during the CT examination, the baby in her belly was illuminated by X -rays.This mother can’t help worrying: Can I do X -ray examination during pregnancy?Does my baby’s baby will have any sequelae in the future?

This expectant mother’s worry is not an individual phenomenon.My friends have experienced similar things.A friend went to the hospital for a head CT because of a headache, but no problem was found out.After a few days, she found that she was pregnant, so she regretted going to do CT and asked me what to do.

In the United States, this situation is not a minority.Every year, thousands of pregnant women will come into contact with radiation.They were frightened, anxious, and even considering killing the children.

Therefore, in order to help friends find out whether pregnant women do X -ray examination will affect the baby, I went to the International Radiation Protection Commission (ICRP) and the US Food and Drug Administration (FDA) to inquire about some information.As a result, I found that in general, in most cases, such concerns are completely unnecessary.

1. Some worries are completely unnecessary

The current medical instruments will pursue accuracy and efficiency.Therefore, when doing X -ray examination, the ray is usually only within a limited range of the body.At this time, X -ray check can be divided into two cases:

1. If you give a expectant mother’s head, oral, chest, legs and arms to shoot CT or X -rays, the rays will not directly look at the baby.Therefore, the effect of X -rays on the baby can be ignored, we don’t have to worry.

2. If the expectant mothers do the X -ray examination of the lower torso, for example, the X -ray examination of the abdomen, stomach, pelvic cavity, lower back or kidney, the baby will be directly illuminated by X -ray, which needs to attract certain attention.

However, this kind of attention is relatively speaking, but there is actually no need to worry too much.This is because scientists believe that the absorption dose of babies in the vast majority of X -ray examination will not exceed 100 milligram (MGY), which will not have a significant impact on the baby’s development.Why do scientists dare to conclude such a conclusion?

2. What does the boundary of 100 mm Gorui mean?

Let’s first explain how much 100 mm Gurui said by scientists.

Giri (GY) is an absorption dose unit for ionizing radiation.In daily life, we will be irradiated with various natural rays. However, the absorption doses they produce are particularly small, most of which are a few micro -Geri or a few pm.

In this comparison, we figured it out. It turned out that the 100 mm Ge Rui (MGY) was already considered a very high dose.In addition, under normal circumstances, doing X -ray inspection will not produce such a high dose.

A large number of scientific studies have shown that only by absorbing the dose more than 100 mm Ge Rui (Mgy) can it significantly change the development of the central nervous system of the fetus and increase the probability of abortion.This is why scientists say that the vast majority of X -ray inspections need not worry.

The data of scientists is to tell us that if a expectant mother encounters an important situation at the beginning of the story, it must be accepted by X -ray (but the dose is less than 100 mm Gurui), or like my friend, I don’t know pregnant pregnancy.When you do the necessary X -ray examinations, you don’t have to worry too much.

When do you need to pay attention?

However, this is not to say that every pregnant mother can use X -ray to be as simple as drinking water to eat.If in some cases, expectant mothers can avoid or delay X -ray examination, I believe that scientists will still support the doctor to consider carefully.So, what are the factors that need to be considered?

Scientists point out that at different stages of pregnancy, the fetal sensitivity to rays is different.In the early stages of pregnancy (3-8 weeks), it was the period of organ development of the fetus. At this time, the fetus was the most sensitive to the rays and the most needed to attract our attention.

After 9 weeks of pregnancy, the fetal organs were initially formed.At this time, the sensitivity of the fetus to the rays will decrease.And with the progress of pregnancy, this degree of sensitivity will continue to decline.

This shows that in the early stages of pregnancy or preparation, expectant mothers need to pay special attention to X -ray related inspections.

What should I pay attention to?FDA gives three suggestions:

1. FDA recommends that before doing X -ray examination, if you find that you have symptoms similar to pregnancy, you must tell your doctor.

2. The FDA also suggested that if you are pregnant with your child or are going to get pregnant, don’t do X -ray inspection of the trunk.

3. If the doctor must do the trunk of the torso because of the emergency condition, you can ask the doctor to ask the doctor a set of lead/lead skirt to cover the uterus and other parts with it.Proposal such as FDA is not to overthrow the previous "100m Gerei below has no significant impact on the development and abortion of the central nervous system", but to reduce unnecessary irradiation and prevent unnecessary risks.

What is "unnecessary risk"?Scientific research pointed out that if the baby’s absorption dose exceeds 10 milligram (if you don’t know how rare 10 milligers are, you can turn up the article again to see the data in the beginning of the chart), X -ray check is indeed indeed indeedThe risk of babies will suffer from leukemia in the future, and it will also increase the wind direction of other cancers in the future.However, don’t worry first. From the picture below, it can be seen that only when it is close to or exceeds 100 milligram, the risk of increased X -ray inspection will become very obvious.This risk will not fall to zero even if I have not done any X -ray examination during pregnancy.

Fourth, pregnancy itself is also an adventure

This data is also reminding us that the process of pregnancy cannot be smooth.Even if the expectant mother does not touch any rays, pregnancy itself will experience certain risks.

In addition, scientists believe that most of the newborn defects and children’s diseases we see are mainly derived from genetic factors and random errors in development.This is also something that cannot be completely avoided in pregnancy.

In short, before the implementation of any medical behavior, doctors must weigh the advantages and disadvantages of them.If an X -ray examination is not very urgent for mothers, doctors can of course delay checking or not check.

On the other hand, if X -ray check is very important and very urgent, then expectant mothers have to understand the choice of doctors.The FDA emphasized that if the doctor is highly recommended for examination because of the urgent condition, the expectant mothers do not do X -ray examination (such as the beginning of this article), then the baby in her belly will be more dangerous, which is much more dangerous than after the X -rays.Essence
